Our Magnetic Finger Charts can be effectively utilized in any beginner band or string class, as well as an intermediate class that might need extra encouragement. They work like a stencil, with holes cut in the magnet where the instrument’s finger holes are located. When applied to any magnetic dry-erase board, the teacher indicates the correct fingering by using a dry-erase marker to fill in the cut-out area. These unique magnets, with normal use, will last for years!
